For those who need a refresher, Magnussen is a Norwegian actor from the comedy television show Underholdningsavdelingen. He and fellow actor Bjarte Tjostheim played Sherlock Holmes and John Watson from the BBC series in the much talked and laughed about parody Oklahomo. The idea for the parody came about when Magnussen noted Tjostheim looked exactly like John Watson, according to an NKR.com article about the parody.
